Butterflies, along with moths (which are dealt with in a separate section), belong to the Order Lepidoptera. There are five families: the Skippers (Hesperiidae), Blues & Coppers (Lycaenidae), Nymphs (Nymphalidae), Swallowtails (Papillionidae), and the Whites and Yellows (Pieridae).
While there are a handful of butterfly species which can be observed on the wing in any month of the year in the Coastal region, the butterfly season is generally from September through to April. Most species will fly for only a part of the season however. Butterflies prefer warm, sunny, calm weather, and it will be much easier to find butterflies in these conditions. Some species also prefer to fly at a certain time of the day. It is often easier to observe certain butterflies at high points in the landscape like hill summits, as their males congregate at such points to set up breeding territories; this behaviour is called hilltopping. Another easy way to find butterflies is to locate flowering plants and watch what butterflies come to visit.
Some of the most commonly observed species around the coast include the Australian Painted Lady, Meadow Argus, Common Brown, Yellow Admiral, and the Black and Imperial Jezebels. In backyard suburban gardens, the Orchard Swallowtail will often be attracted to citrus plants and Cabbage Whites will be drawn to brassicas. Any patch of grass lawn will attract Common Grass-blues.
When taking photos of butterflies, it is most helpful to obtain images of both the upperside (dorsal) view of the wings, in addition to the underside (vestral) view of the wings. This makes the identification process much easier for some of the hard-to-identify species. If possible, including features of the butterfly's surrounds for context can be helpful in determining the relative size of the butterfly. Bear in mind that as a butterfly ages, it can become quite tatty and faded, so that it may have chunks of a wing missing, or appear much paler than it otherwise appears in photos.
Caterpillars, pupae, adults
Butterflies are the adult stage of the life cycle (so it's important to note that if you see a small butterfly, it is not going to grow into a larger one, it will stay the same size!). Adult butterflies are the life stage responsible for the reproduction and dispersal of the species; the females lay eggs singly or in clusters on or near the larval food plant; the eggs then hatch into larvae (caterpillars), which are the life stage responsible for eating and growing; these then form a pupa (chrysalis), where the larval stage transforms into the adult butterfly. Some species will overwinter as eggs, or as larvae, or as pupae. Some species are migratory and do not breed here at all, and some species are only occasional vagrants to our area.
